SPECIFICATION forming part of Letters Patent No. 305,679, datedSeptember 23, 1884.

'Application filed January 29, 1884. (No model.)

have invented certain new and useful Irn provenients in Check-Bowers;and I do de- Clare the following to be a full, clear, and'eX- actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying draw` ings, and to letters or figures of referencemarked thereon, which form a part of this v specification.

Figure l of the drawings is a representation of a front view of mydevice. Fig. 2 is aplan view of the same. Figs. 3, 4, 5, and 6 aredetail views.

This invention has relation to check-rowers for seedplanters; and itconsists in the construction and novel arrangement of deviceshereinafter set forth, and pointed out in the claims appended. l.

In the accompanying drawings, the letter A designates the transverse barof the frame, having the end pieces or arms, B, which are braced to themain bar by means Vof the irons C. Each arm B carries at one end aguide-pulley, D, and at the other enda guide pulley, E, for the iield-cordL Each arm B also carries a bearing, F, underneath for thetransverse shaft G, which extends under the main bar A, and through acenter bearing or hanger, II, extending downward from said bar.

On each end of the `shaft G is rigidly secured the large grooved wheelK, under 4o with radiallyextended arms a, arranged inV which theeld-cord passes, engaging its under portion. This grooved wheel isprovided pairs at diametrically-opposite portions of its diameter, andserves to engage the knots or obstructions ofthe eld-cord as the plantermoves over the field. i

L represents a short lever-arm, which is pivoted to a bearing of themainl bar at b, and is designed to engage the seed-slide. This arm isslotted at c to receive an adjustable eyebolt, d, to which is attached aconnecting- 5o rod, e, which extends to a slide-bearing, f,

which is seated in an arc-slot, g, in the upper adjustable section, h,of a pivoted swinging regulator, M. The section h is slotted, andissecured to the arm 7c of the regulator M by means of a bolt and nut.Suitable adjustable stop-screws, Z, are provided to project into theends of the arc-slot g, as shown in the drawings. The regulator ispivoted to the central hanger, H, which depends from the main bar, andbelow the pivot are cam-shaped arms or wings m, extendingllaterally, asshown in the drawings.

On the stem l? of the swinging regulator is a weight, w, which isadjustable, and is se.

cured in position, after adjustment, by the setscrew o.

On the shaft G, at each side of the central hanger, H, is secured ahead, t, carrying a projecting arm, s. These arms-which extend at rightangles and in opposite directions from the shaft G, are of sufficientlength to engage the respective lateral wings of the swinging regulatoras the shaft revolves. As the planter moves over the field, the shaft iscaused to revolve by the field-cord, which engages Athe grooved wheelatthe end thereof, and as the arms s are set in the shaft in suchposition that when the wheels K are turned to bring their knot-engagingarms a into vertical position the shaft-arm s will be horizont-al, andono y of said arms, s,will be engaged with one of the wings of theswinging regulator M. This position will be maintained until the arms aof the grooved wheel engage a knot or obstruction of the field-cord,when the shaft will be turned, vibrating the regulator and throwing thelever-arm L and the seed-slide to which it is connected.
